Continuity mistake: As the Munchkins send Dorothy off singing "We're off to see the Wizard" the red coated guard is hanging out of his booth as he waves his sword. In the next shot he's inside the booth tapping time with his sword. (00:33:30)
Revealing mistake: Throughout the movie, you can tell that if the main characters walking into the distance, the "faraway" landscape is a giant matte painting. (00:33:35)
Revealing mistake: As Dorothy is about to walk into the cyclorama (backdrop) as she leaves Munchkinland, Munchkins are blurred, including a Munchkin soldier on the very far right, who becomes transparent with the matted-in flowers. (00:33:40)
Revealing mistake: When Dorothy first meets the Scarecrow, he is placed up on a wooden stick and you can blatantly see the wire holding him up on it. (00:33:40)
Audio problem: When the Scarecrow says "You see, it's very tedious being stuck up here all day long with a pole up your back," his mouth is saying something else. (00:33:50)
Continuity mistake: When Dorothy first meets the Scarecrow there are no pumpkins on the left side of the Yellow Brick Road. Later when he starts to dance pumpkins have been added. (00:33:55 - 00:36:50)
Continuity mistake: In the scene where Dorothy meets the Scarecrow, there are no pumpkins on the ground while the Scarecrow is tied to the pole. After Dorothy gets him down, pumpkins are then everywhere behind the place that he fell. (00:34:00 - 00:35:45)
Continuity mistake: As she talks to the Scarecrow, Dorothy says to Toto, "Wasn't he pointing the other way?". In several of the close up shots wind is blowing her hair around and in others it isn't. (00:34:30)
Continuity mistake: When Dorothy first spots the Scarecrow the piece of rope hanging off his left arm is about 1 inch long. Without touching it a few shots later it's grown longer by about four or five inches. (00:34:30)
Continuity mistake: When Dorothy is talking to the Scarecrow for the first time, the Scarecrow moves further down his pole between close up shots. (00:34:35)
Continuity mistake: The rope around the Scarecrow's neck is tied differently throughout the scene after he meets Dorothy. The rag around his hat is rearranged also. (00:34:50 - 00:36:20)
Continuity mistake: As Dorothy and the Scarecrow exchange, "How do you dos" the straw coming out of the left side of his shirt triples between shots. (00:35:05)
Continuity mistake: During the sequence where Dorothy meets the Scarecrow, Dorothy's pigtails are first short (above her shoulders) and as the song progresses her hair gets longer (below her shoulders), then short, and then long again. (00:35:15)
Visible crew/equipment: The apparatus on the Scarecrow's chest that's attached to the wires above his head can be seen sticking out in several shots as Dorothy walks up to him. (00:35:30)
Audio problem: Just before Dorothy lets the Scarecrow down, his lips don't match what he is saying. (00:35:35)
Revealing mistake: The Scarecrow tells Dorothy to, "just bend the nail down in the back and maybe I'll slip off" but what she actually does is pull a lever. (00:35:40)
Suggested correction: I have the scene up right now, and the nail on the pole just looks like... a huge nail. Then Dorothy bends it, and the Scarecrow falls off. I'm not denying that it's a lever, because it's entirely possible that it is. The thing is, there is nothing in the scene that indicates that it absolutely has to be a lever, and it can't be a nail at all.
Audio problem: The very last line of the scarecrows song "Life would be a ding-a-derry if I only had a brain" does not match with the scarecrow's mouth movements, probably because he's too busy concentrating on his dancing. (00:35:55)
Visible crew/equipment: When the Scarecrow says, " Did I scare you?" the camera's shadow can be seen on Dorothy's face. (00:36:00)
Continuity mistake: The strand of straw that the crow pecks from the Scarecrow's lapel was not there before, as shown by previous close-ups. (00:36:00)
Continuity mistake: When Dorothy says, "No, I just thought you hurt yourself" she takes her hand off the Scarecrow's shoulder. In the next shot her hand is back on his shoulder. (00:36:00)
